An unimpactful "insult" invented by left-wing incels, it's derived from
Chad but it's supposed to be... errr... 'chud'.
It was supposed to be the left's answer to the hurtful and memetic insults that the
right invented to describe the left such as
soyboy, tranny, troon, NPC, incel, etc., except "chud" just sounds weak and hasn't caught on in the mainstream despite years of being spammed and forced into online discourse, so now it's mostly used ironically by
right-wingers to make fun of each other, but you'll see terminally online left-wing people use it unironically.
"
Ugh, the
right are funnier than us and they can actually meme... we need to come up with an insult so we can fight back... I got it! it's
chad, but with a u... CHUD! CHUD!"
"Actually, children CAN consent to sex... CHUD!!!"
"Look at that guy lifting weights... w-what a chud"
